In recent years, social issues related to the environment, such as climate change due to theimpact of global warming, resource depletion due to population growth and marine
pollution due to plastics have become increasingly serious. As a movement of theinternational community toward the environment, it is necessary to tackle these issues on a
global scale.
In response to this situation, the United Nations General Assembly issued the "Sustainable
Development Goals (SDGs)" in 2015, which agreed on 17 goals and 169 targets that should
be addressed for a sustainable world, including environmental conservation, such as“Taking urgent action to combat climate change and its impacts" and “Ensuring sustainableconsumption and production patterns" and called for active involvement of companies aswell as the national government.
In our medium-term plan, we clearly set out the relationship between “Efforts to address E(Environment), S (Safety), and G (Governance)” and the SDGs. We will continue tocontribute to the development of society through our business activities in response toincreasingly complex and serious social issues.
In December of the same year, the "Paris Agreement" was adopted at the International
Conference “COP21” of the United Nations Framework Convention on Climate Change(UNFCCC), and the movement toward decarbonization is accelerating in Japan andoverseas. Companies are required to understand the risks and opportunities posed by climate change to their businesses, set long-term
reduction targets, and work to reduce greenhouse gas emissions throughout the supply chain. It is also expected that local communities,
companies, and the whole world will work together to resolve important environmental issues
Under these circumstances, companies are playing an increasingly important role in solving environmental problems, and it is essential
to respond to the various requirements and needs of society.
Nakanishi Inc. (hereinafter referred to “NSK”) recognizes that addressing global environmental issues such as climate change is one of
the most important management issues. We will use our accumulated know-how and advanced technological capabilities to show
solutions to environmental problems. We will build a foundation for achieving the SDGs by steadily advancing activities such as
strengthening legal compliance, reducing the environmental impact of manufacturing, promoting environmental education andcommunication, and conserving biodiversity.
Recognizing that preservation of the global environment is one of the most important issues for all humankind, we will contribute to the
reduction of greenhouse gases in society as a whole by working to reduce greenhouse gases in manufacturing and providing
high-performance products and services that are energy-efficient and lead to reductions in emissions during use.
We will also work to reduce greenhouse gas emissions, recycle resources, and manage chemical substances throughout the product life
cycle to reduce the overall environmental impact.
As a company that contributes to the global environment, we have set the goal of "coexistence between people and the earth," and we
intend to combine the technological and creative capabilities we have cultivated over the years to achieve both the resolution of social
issues and business growth, thereby contributing to the creation of a brighter future. We appreciate your continued support.
NSK will provide the best value to stakeholders by passing on environmental activities to the next generation and comitting continuous
improvements to develop our business.

We have 256 sunlight panels on the southern sidewall of NSK Wing G.
Annual power generation is approximately 33,000 kw, equivalent to approximately 8 residential housing, and is used for lighting in Wing G.

■ Introduction of the automatic control system to the company's air conditioners in FY2015
We introduced the automatic control system for the air conditioners, which randomly stops operating for 3 minutes per 30 minutes.
This have reduced power consumption of the air conditioner by 10%.
C in summer and 21 °C in winter.
The temperature of the air conditioners is set to 28 °■ Active introduction of hybrid vehicles
With a few exceptions, we have actively introduced hybrid vehicles with less environmental impact than gasoline vehicles to ourheadquarters plants and each offices. As a result, CO2 emissions associated with driving have decreased by 34% compared with
2.0 L gasoline vehicles.

■ Operation of R&D Center (environment-friendly building)
The R&D Center building, a new headquarters building that started operation in April 2017, is designed for environmental
compatibility. It incorporates environment-friendly materials and structure of exterior walls and equipment such as lighting and air
conditioners. We have also introduced a central monitoring system to check each management value remotely at all times.

Lighting
All buildings are equipped with LED lighting, partially with a human sense sensor, which
prevents forgetting to turn them off for energy conservation.

Planting
We have planted more than 300 of 10 different trees and seeds, including cherry trees, zelcova
trees and grasses, outside the building to develop rich green walkways and gardens.
We also landscaped the prefectural land in front of the main gate by planting ground-cover plants
such as hedelas and other seeds. In addition, environmental beautification activities such as
regularly picking up garbage on the surrounding roads are carried out.

Underfloor air conditioning by floor cooling/heating
In large spaces, such as entrances, showrooms and the Center Coat with a four-story atrium, thefloor cooling/heating system using abundant groundwater works with the underfloor air
conditioners to make residential spaces comfortable and achieve high energy conservation.

■ Operation of the A1 Factoty
March 2018, we began operation of the A1 Factoty, we have integrated a number ofprocesses from machining parts to finishing to build up an optimized production linewith fewer wastes and losses. This increases production capacity and substantially
improve product quality and production efficiency.
Energy consumption is one of the environmental impacts of the A1 Factoty. As 70%
of total energy is consumed in the A1 Factoty, we have been promoting energy
conservation initiatives, including the proper operation of compressors, reduction of
air consumption, and optimization of the collection ability of dust collectors, together
with the production engineering department and the parts processing department.
In addition, the A1 Factoty provides employee-friendly facilities by constantly
collecting and processing oil mists scattered in work spaces.
As a global company, we will continue to timely provide innovative and impressive
products through our manufacturing activities, while considering local environment
and work environment.

Green Products Activities■ Product information
Here are some of the main products.

Medical/ Industrial Products
NSK develops products that have the maximum value and the minimum environmental impact.
We are striving to develop products that are lighter, more compact, and more efficient in order to realize an environmentally friendly
and people-friendly society by making the most of technologies available through our corporate activities, and provide productsthat are friendly to the global environment.

effective use of limited resources.

Downsizing
Making products compact leads to a reduction in packaging
materials and raw materials used in products.
We also believe that it is effective for energy saving in logistics
because it enables many products to be transported with low
energy consumption.

Efficiency of cleaning function
Our maintenance equipment can efficiently clean multiple
products at one time. We believe this reduces the energy costof product cleaning and has a significant effect on product life.
In addition, by quantitatively managing the cleaning liquid
used for cleaning, it is possible to reduce the running cost of
the cleaning liquid and reduce raw materials.
